Answer:
B. 8 x 10^3
Step-by-step explanation:
1.6 x 10^5 / 0.2 x 10^2
= 160 000 / 20
= 8 000
You can write this as 8 x 10^3
Use distributive property:
(a + b)(c + d) = ac + ad + bc + bd
(y + 1)(y² + 2y + 3) = (y)(y²) + (y)(2y) + (y)(3) + (1)(y²) + (1)(2y) + (1)(3)
= y³ + 2y² + 3y + y² + 2y + 3 = y³ + (2y² + y²) + (3y + 2y) + 3
= y³ + 3y² + 5y + 3

Answer:
Option B
Step-by-step explanation:
Surface area of a cone is given by the expression,
V = πr(r + l)
Here, r = Radius of the circular base
l = Lateral height of the cone
By substituting the given values in the given expression of volume,
V = π(8)(8 + 15)
= 184π units²
Therefore, surface area of the given circular cone is 184π units².
Option B is the correct option.
